Original application Feb. 16, 1960, Ser. No. 8,649, new Patent No.3,200,888, dated Aug. 17, 1965. Divided and this application Feb. 25,1963, Ser. No. 268,209

17 claims. (Cl. 19s s0) This invention relates to Marshalling Apparatus,and more particularly to improved apparatus for marshalling a mixture ofobjects or articles into a single file column or columns and advancingthe columnized articles in individually spaced order and in conditionfor convenient and rapid classification and separation into classes orgroups of different characteristics. This application is a division ofour copending application Serial No. 8,649 filed February 16, 1960, nowPatent No. 3,200,888, issued August 17, 1965.

The reliable and efiicient separation and classification of a mixture ofrelatively solid articles, objects and products into predeterminedgroups or classes in accordance to size, shape, composition or otherinherent characteristics, often requires that the mixed objects be firstmarshalled into single file columns and advanced in uniformly spacedorder to sensing and classifying mechanism of the processing system. Insuch processing systems, the article marshalling and advancing apparatusshould also be capable of sifting out and removing undesired debrisattached to or entrained with the articles prior to classificationthereof. For example, in the processing or harvesting of fruit and rootproduce, such as potatoes, sugar beets, turnips, onions and likeunder-ground produce, or apples, oranges, peaches and like crops grownabove ground, the objects or produce often have entrained therewith orclinging thereto, underised vegetation, stems, twigs or vines, and/ orstones, hard lumps and soil clinging thereto, which should be removedprior toclassification of the objects or produce.

It is the purpose of this invention to provide apparatus for efficientlyand reliably marshalling and advancing a mixture of articles or objectsof varying size, shape and composition into a column or columnstraveling in single file and individually spaced order.

A further purpose of this invention is to provide improved apparatus formarshalling and advancing an assortment of objects in single filecolumns and in uniformly spaced order, and during such advance to siftout and remove undesired debris entrained therewith or clinging thereto.

While the marshalling apparatus of this invention is uniquely adaptedfor aligning and advancing a mixture of relatively solid organic orinorganic articles, objects or products of varying size, shape andcomposition into single file and spaced order preparatory to processinginto predetermined groups or classes, this invention will be exemplifiedin the following description to the marshalling of a mixture ofpotatoes, stones, clods and sod in single file and individually spacedorder to insure effective classification and separation of the desiredpotatoes from the undesired stones, clods and sods mixed therewith.

The harvesting of potatoes in an economical manner by machine operationpresents numerous difiicult and varied problems, resulting from variablefield conditions under which the mechanical harvester must operate. Manysandy and gravelly soils especially suitable for potato growing, oftencontain numerous stones of various sizes which are excavatedwith thepotatoes, and which should be promptly eliminated during the harvesting,to avoid bruising damage to the harvested potatoes. When the harvestingmust be performed when the soil is dry ice and hard, or under otherunfavorable soil or climatic conditions, soil lumps and clods are oftenexcavated with the potatoes of such hardness that they will not crumbleduring normal conveyor handling, and should be eliminated during theharvesting process if potato bruising is to be avoided. Many potatofields at the time of harvesting are also contaminated with tenacioussod and weed root growth, which is excavated with the potatoes and whichshould also be separated and discarded during the harvesting process.

The marshalling apparatus of this invention is particularly adapted formounted association with self-propelled root and potato harvesters,provided with one or more digging or excavating shovels which transferthe excavated material on to a primary sifting conveyor which sifts outsoil, stones, sod and other debris which is smaller in size than thesize range of the root crop to be gathered; followed by a primarydeviner for removing the stripping out above-ground growth and vinesfrom the product stream. The harvester is also desirably provided with asecondary sifting conveyor extending transversely of the harvester andoperative to sift from the product stream, such stones, clods and sodwhich are larger than the largest size root product or object to begathered.

The product stream is discharged from the secondary sifting conveyorinto a collecting area of bin, and may be composed of a mixture ofpotatoes and remaining debris such as stones, hard clods and sod of thesame size range as the root crop to be gathered and not previouslyeliminated.

The marshalling apparatus of this invention may be constructed as anintegrated mechanism which can be mounted on the framework structure ofthe harvester, for conveying and marshalling the potatoes and stones,clods and sods of similar size from the receiving bin to the rear end ofthe harvester, in a series of single file columns, and in a manner whichpermits the selective elimination of the stones, clods and sods from thepotato stream. The marshalling system includes a series of columnizedadvancing paddles connected to and advanced by one or more driven chainsor belts. The paddles in each paddle column are arranged in linearspaced relation, and each paddle presents an object advancing facedesigned to positively advance only a single potato, stone or clod in anupwardly inclined longitudinal direction toward the rear end of theharvester.

One or more tumbling rolls are arranged in operative association witheach paddle column, and which provides partial or total support for theobjects advanced by the linearly spaced paddles. Each of the columnizedadvancing paddles operates to withdraw one or more objects from thereceiving bin, and advance the same in tumbling contact with theassociated rotating marshalling roll or rolls. Each columnized advancingpaddle is so shaped and dimensioned as to support only a single objecton the advancing face thereof as the paddle reaches the upper end of itstravel. If more than one object is initially engaged by an advancingpaddle, the extra object is tumbled laterally from the advancinginfluence of the paddle for return to the receiving bin for subsequentpick-up. The tumbling movement to which the objects are subjected duringtheir columnized upward travel through the marshalling system, serves tobreak off any soil which may still clingthereto.

Where only a single marshalling roll is employed in association witheach paddle column, the marshalling roll may be positioned directlyunder the line of travel of the columnized paddles to provide tumblingsupport for the objects advanced thereby. Alternatively, the marshallingroll may be positioned to extend along one side of the line of travel ofthe columnized paddles to effectuate Patented July 5, 1966 tumbling ofthe objects, with a stationary supporting plate positioned under thepaddles to provide support for the paddle advanced objects.Alternatively, a pair of tumbling rolls may be associated with eachpaddle column to provide tumbling support for the paddle advancedobjects. Longitudinally extending bafile plates may be provided toassist the channelization of the advancing objects into linearizedcolumns. Where vines and other growth debris is so prolific that thesame cannot be adequately eliminated by a primary deviner, a secondarydevining roll in riding association with the tumbling roll may beprovided to insure complete removal of remaining vine and growth debris.

When the mixed articles or objects have been arranged in single filecolumns and individually spaced relation by the combined action of theadvancing paddles and marshalling rolls, mechanism positioned adjacentthe dis charge end of each column may be provided, which is operative toselectively detect the characteristics of the individually advancedobjects and thereupon separate them into the desired classifications.

Other objects and advantages of this invention will become apparent asthe disclosure proceeds.

The marshalling apparatus of this invention can be advantageouslyconstructed as an integrated unit adapted to be stationarily positionedto formya component part of a plant or warehouse installed processingline, or mounted on the body of a traveling vehicle.

The marshalling apparatus generally comprises an object marshalling andadvancing assembly 10 as shown in FIGS. 3, 4 and 5, which operates towithdraw a mixture of objects of substantially different electricalconductivity from a receiving area or bin 40, marshal-l the withdrawnobjects into one or more columns, and advance the columnized objects inindividually spaced relationship and successive order into the presenceof a sensing device 60 as illustrated in FIG. 2.

The marshalling and advancing assembly illustrated in FIGS. 2, 3, 4 and5, embraces a series of upwardly inclined and parallel extendingcolumnizing troughs, each composed of a longitudinally extendingtumbling roll 45 and an adjacent spinner roll 46 defining a columnizingtrough therebetween, and which are rotatably driven from the lower endthereof. A continuous paddle equipped object advancing and marshallingchain 20 driven from the lower end thereof, withdraws objects from thereceiving area or bin 40 and advances a column of articles along theadjacent trough while the columnized objects are tumbled during advanceby the rotating tumbling roll 45 and adjacent spinner roll 46, therebyserving to marshall the colu'mnized objects in single file andindividually spaced order when they reach the upper end of the troughformed by the tumbling roll 45 and adjacent spinner roll 46 fordischarge into the inner tube 61 -of the sensing ring 62 as shown inFIG. 2.

In the alternate form of marshalling and advancing assembly shown inFIGS. 1520, the trough forming tumbling roll and adjacent spinner roll126 in paired arrangement are rotatably driven from the upper endthereof, and a single object advancing chain 20a extends therebetween,driven from the upper end thereof, and equipped with spaced objectadvancing paddles extending from both sides thereof. Thus a single chain20a with object advancing paddles extending from both sides thereof,operates to advance two columns of objects along the paired tumbling andspinning rolls positioned on opposite sides of a single object advancingchain.
